To all cli/wm 'it may concern:

Be it known that I, CHARLIE W. DYER, a citizen or" the United States,residing at Stratton, inthe county of Franklin and State of Maine, haveinvented certain new and useful Improvements in Oil-Vaporizers for`Explosive-Engines, of. which the following is a specification.

This invention relates to .engine starters, and more particularly `to a.vaporizing device tor supplying an explosive mixture to' the cylinder ofa cold engine so as to enable the saine to be started.

Great diiiiculty is frequently experienced in starting gas-engines afterthey have cooled, due to the fact that. the explosive mixture whicliissprayed into the cold cyl` inder quickly condenses so as to render itvery difficult to ignite the same. One o't' the v main objects of myinvention is to eliminate this ditliculty by providing means torsupplyinp an explosive mixture to the cylinder in vaporous form. Afurther object is to provide means of simple construction and operationfor producing,- this' vaporous mixture. Further objects will appear fromthe detail description.

ln the drawings Figure l is a central vertical sectional view throughthebyaporizing means.

Fig. 2, is a section on line 2-2 of Fig. l.

The numeral l designates a cylindrical chamber or casing in the lowerend of which is threaded a cylindrical plug- 2 ofhard rubber or othersuitable electrical insulating material. The casing l is provided, atthe upper end, with an integral laterally extending nipplev the outer'end of which is externally threaded, as at 3, so as to be at` gasengine. is provided with a terminal post l secured therein and. threadedto receive a securing nut 4a. This post is con` nected by a lead 5 tothe lower end of a coil 6 mounted. in the casing` l a short distance toone'side of the center thereot'. This coil is made of German-silver wireor' suitable gage, or other suitable material. The coil 6 is 'elongatedso as to extend to within a short distance of the upper end ot' thecasing. The

'lhe rod S and the. post 4 areconnected to the The plu r 2 kthiskerosene vapor is compa" wires l0 and1l, respectively?, which are connected to the opposite side of anelectric batu tery, not shown. A suitable switch may be interposed inone of the wires. By closingthe switch a current/sot electricity will becaused to flow from the battery through the coil 6 so as to heat thesame to a high tern= perature.

A fuel sup ily pipe l2 is threadec nrougli' the upper end of cylinder@with its lower end in vertical 'alineinen with the coil (i.
